A new control topology of information reliable spread

High reliable multicast service is a new information transfer service mode based on IP route. The implement of reliable multicast depends on the control topology structure. With the analysis of control topology structure of the current logical hypercube based reliable multicast protocol, this paper brings forward a new reliable multicast control topology structure-ComCube. The feature of the structure is analyzed such as scalability, fault tolerance, length of multicast route, nodes' load, stability and maintenance. The analysis shows that ComCube has good scalability, balanced nodes' load, stable structure and it can be established easily and maintained expediently.
